Context: Curious George, a book by H A Rey  (Anyone stlll have a copy? Or anyone’s children, or grandchildren?)
On page 31 are two pictures, one above the other. In the first the Man in the Yellow Hat is sitting at his desk dialing the telephone; George is watching. In the second, the man has left, and George is standing on the same chair at the desk, imitating, dialing the telephone.  What fun!
On the desk are three items: 1) a telephone 2) a semicircular block with a handle on top and a blotter on the rounded bottom 3) a thing which is a three-inch circular one-inch-high base, with a foot-long stick stuck into it that curves to horizontal at the top, and hanging from it is a four-inch string attached to a –-
That’s the question.  What is that gizmo?  The telephone is an old one, and I recognize the blotter, but what’s hanging from the string?
Anyone familiar with the book and still have access to it?
